Abstract:The congressionally mandated National Bridge Inspection program requires States to periodically inventory, inspect, and rate all highway bridges on public roads. The National Bridge Inspection Standards, implemented in 1971, prescribe minimum requirements for the inspection of highway bridges in the United States. Visual inspection is the primary tool used to perform these inspections. A survey was conducted to help determine current policies and practices that may affect the accuracy and reliability of visual inspection. The survey had three main objectives. The first objective was to compile a state-of-the-practice report for bridge inspection, particularly as it pertains to visual inspection. The second objective was to gather information on bridge inspection management to study how inspection management may influence the reliability of inspections. The final objective was to gather data about the current use of nondestructive evaluation technologies and to identify current and future research needs. Results from the questionnaires are presented in a question-by-question format. The motivation behind each question and the response percentages for each question start the discussion, followed by the results obtained. Included within each question are comments that will highlight the results. 84 p.
